As controversial as it is, the online prediction market Polymarket has, since its inception, created a set of millionaires, whether by luck, skill, insider knowledge, or pure mechanical precision. The latest such story emerged in early 2026 as it became apparent that a trading bot managed to turn $313 into $438,000 within a single month.
Specifically, a profile designated 0x8dxd unleashed a trading bot onto the prediction market in December 2025 with $313 and the mandate to execute numerous directional bets regarding major cryptocurrencies.
By press time on January 6, the profile has an almost flawless win rate of 98% and has made approximately $437,600 in profits within just one month.
How did the trading bot turn $313 into $438,000 in a month
The strategy appears to be dependent on continuous watching of the market – primarily Bitcoin (BTC) spot prices on cryptocurrency exchanges Binance and Coinbase (NASDAQ: COIN) – and lightning reflexes.
Indeed, when the price movements already all but confirm direction, but Polymarket’s systems are yet to account for the growing certainty, the bot invests in the option almost guaranteed to win.
Perhaps the most impressive thing about the strategy is its simplicity and evasion of hubris. With each trade, the strategy is static, and gains are capped. Still, as evidenced by the gap between the starting budget and winnings, volume both helped accrue massive profits and made the few losses insignificant in the grand scheme of things.
Lastly, at press time, the total position held by the profile amounts to about $77,400, and, by press time, the single biggest ‘win’ bought in approximately $13,300. Polymarket’s interface displays that 0x8dxd has, so far, made 6,615 predictions.
